Grids & Integration

The level of new solar capacity – 8,263 MW – however, was 15.5% down from the 9,782 MW added in 2017 owing to safeguarding duty and tax taking a toll on large-scale PV. While utility-scale solar declined 23% year-on-year, rooftop PV remained a bright spot, and registered impressive growth of 66%.

An international team of economists says power-to-gas may already generate hydrogen at costs competitive with fossil fuel power plants in Germany and Texas, provided certain production output levels are not exceeded. If medium and small power-to-gas is competitive, large-scale should be viable by 2030.

In the run-up to the Energy Storage Europe conference pv magazine is featuring the top ten developments in the field as our Energy Storage Highlights, selected by an independent jury of experts. Last week we revealed #6, a ’70s revival of a ceramic high temperature battery.

A European energy system powered solely by renewables is economically feasible, according to a study which suggests decentralized energy systems operating within the framework of a stronger pan-European energy trade could reduce the cost of electricity from the €69/MWh price seen four years ago to around €51 in 2050.

Portugal’s government has approved its 2018-2027 plan to strengthen its grid to integrate large volumes of renewable energy. Environment minister João Matos Fernandes has also revealed the solar auction planned for next summer will offer around 1.75 GW of capacity.

The module maker and electronics giant is testing the feasibility of a complex virtual power plant with a blockchain platform provided by US-based LO3 Energy.

While solar is lauded as a cheap energy resource in OECD countries, the cost of financing PV projects in developing nations has impeded progress. Development banks and the Clean Technology Fund they finance have played a key role in providing access to cheap financing for clean energy projects in many markets.

That was the one of the main conclusions reached among 400 attendees at the Solar plants in Spain: development, financing and energy future conference, organized by Soltec and PV association UNEF in Madrid this week.

IHS Markit’s analysts have mapped out what they are keeping an eye out for in the year ahead. Aside from higher installation figures, the number-crunchers predict a continued battle for multi-function in the hard-fought inverter segment and a potential watershed year for utility-scale storage.

The legislation would enshrine a customer’s right to generate and store electricity as well as to connect to the grid without undue burden and would provide freedom from discriminatory fees and set compensation for battery power exports.
